I shipped the same amount of fabric to two places---one Ohio, one Quebec. The package going to Ohio was $4.95, the one going to Canada was over $11. From where I live Canada isn't that much farther than N.E. Ohio. Ridiculous. My husband ships and recieves RC plane parts from all over the world---shipping rates from Hong Kong to here aren't near as much as the reverse.
Have you check out Marshall's Dry Goods? Their pricing is so low that you can pay more for shipping and still get a good deal. Of course, I don't know about the shipping charges to Canada but it's worth a try. They have bundles of 17 (I think it might be 11, I can't remember) 5 yd blenders for only $102.
